m0useanswered grow question 2 months ago I don't see a diary on your profile for these ones.
But if they are photoperiods they should not be entering bloom unless your giving them an uninterrupted dark period of around 12hrs. If you can confirm they are photo's and the the dark period is less then 9hr they should not do that. something got mixed up.
Maybe its a newage "fast" version and they mix them with autos. sometimes they come out all auto vs fast.
Now if they are both auto flowers, their is nothing you can do. autos do w/e the fuck they want and bloom when they want. Best thing you can do it use LST to keep the plant short.
One last option I can think of is if one of them photoperiods are from outside and flowered cuz the light period was different, and if its added back into the tent with longer light cycles it will start to reveg and get crazy growth and exit bloom, this is stressful on the plant. but if this did not happen and they not autos. their is just no solution other then to grow it out.
